[PATCH 0/2] riscv: dts: spacemit: Add initial support for Milk-V Jupiter

[Javier Martinez Canillas]

Hello,

This patch-set adds a minimal support for the Milk-V Jupiter board.
which is a Mini ITX computer based on the SpacemiT K1/M1 RISC-V SoC.

The DTS is very basic but at least allows to boot into a serial console
and get UART output, similar to what exists for other K1 based boards
such as the BananaPi BPI-F3.

Patch #1 just adds the compatible string for the Milk-V Jupiter to the
SpacemiT bindings and patch #2 adds the minimal DTS for this computer.

Best regards,
Javier

[PATCH 2/2] riscv: dts: spacemit: Add Milk-V Jupiter board device tree

[Javier Martinez Canillas]

Add initial support for the Milk-V Jupiter board [1], which is a Mini ITX
computer based on the SpacemiT K1/M1 Octa-Core X60 64-bit RISC-V SoC [2].

There are two variant for this board, one using the K1 chip and another
using the M1 chip. The main difference is that the M1 can run at a higher
frequency than the K1, thanks to its packaging.

For now, only a DTS for the K1 variant is added since there isn't support
yet for the X60 cores operating performance and thermal trip points.

The support is minimal, but at least allows to boot into a serial console.
